Description
Technical field
This utility model relates to pipe network monitoring field, particularly to a kind of pressure-regulating device in pipe network monitoring system.
Background technology
Underground pipe network is complicated is distributed in Urban Underground, and the user being in zones of different is different to each self-corresponding pipeline requirement, and the Supervisory control equipment of zones of different also has different requirements to pipeline.Such as, the flow media pressure in some pipelines is excessive causes monitoring device degree of accuracy the highest or causes monitoring device to be damaged.Therefore, be badly in need of in pipe network monitor system a kind of can the device of on-demand regulation pressure.In prior art, typically realized by the opening degree of control valve, but such result is that the pressure medium in pipeline is unbalanced, particularly the medium moment by valve, easily cause pipe vibration.This vibrations are abnormally dangerous for inflammable and explosive media such as combustion gas.In addition, the method for above-mentioned regulation pressure not can determine that instantaneous delivery value, adds the difficulty of follow-up monitoring work to a certain extent.
Utility model content
This utility model purpose is to provide a kind of pressure-regulating device in pipe network monitoring system, solves manifold pressure adjusting means regulation in prior art inaccurate, function singleness, it is impossible to meet the technical problem of Supervisory control needs.
The technical solution adopted in the utility model is: a kind of pressure-regulating device in pipe network monitoring system, including:
By cylinder entrance, oblate cylinder fuselage, the housing of cylinder outlet composition；
The impeller being made up of some blades, the rotary shaft of impeller is coaxially disposed with fuselage, and the blade tip of blade and the distance of fuselage side wall are 1-2 millimeters, and rotary shaft stretches out fuselage；
The half elliptic resistance gauge at fuselage inwall top it is hinged on by articulated elements, the arc section surface of resistance gauge and blade sliding contact, the resistance gauge back side is provided with regulating part away from one end of articulated elements, one end of regulating part is fixing with resistance gauge to be connected, the other end stretches out outside fuselage, rotates regulating part and resistance gauge can be made to rotate around articulated elements；
Being arranged on rotary shaft and stretch out the measuring device of one end, measuring device includes that tachometric survey device and display, tachometric survey device are connected with display.
Further, the blade tip of blade and the distance of fuselage side wall are 1 millimeter.
Further, tachometric survey device is angular displacement sensor.
This utility model provides a kind of pressure-regulating device in pipe network monitoring system, the pressure in pipeline is controlled by controlling the rotary resistance of impeller, medium is made to pass through pressure during valve uniform, it is to avoid rocking of pipeline, safer when making pipeline conveying flammable and explosive substance.And, coordinate the regulation of wheel speed, make pressure more accurate.In addition, moreover it is possible to the instantaneous delivery of medium is monitored, reduce follow-up monitoring difficulty, provide for system and monitor data the most accurately.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of pressure-regulating device in pipe network monitoring system in this utility model；
Fig. 2 is the left view of a kind of pressure-regulating device in pipe network monitoring system in this utility model.
Detailed description of the invention
As shown in Figure 1-2, a kind of pressure-regulating device in pipe network monitoring system, including:
By cylinder entrance 1, oblate cylinder fuselage 5, the housing of cylinder outlet 7 composition；
The impeller being made up of some blades 6, the rotary shaft 8 of impeller is coaxially disposed with fuselage 5, and the blade tip of blade 6 is 1-2 millimeter with the distance of fuselage 5 sidewall, and rotary shaft 8 stretches out fuselage 5；
The half elliptic resistance gauge 3 at fuselage 5 inwall top it is hinged on by articulated elements 4, the arc section surface of resistance gauge 3 and blade 6 sliding contact, resistance gauge 3 back side is provided with regulating part 2 away from one end of articulated elements 4, one end of regulating part 2 is fixing with resistance gauge to be connected, the other end stretches out outside fuselage 5, rotates regulating part 2 and resistance gauge 3 can be made to rotate around articulated elements 4；
Being arranged on rotary shaft 8 and stretch out the measuring device 9 of one end, measuring device 9 includes tachometric survey device 92 and display 91, and tachometric survey device 92 is connected with display 91.
Further, the blade tip of blade 6 is 1 millimeter with the distance of fuselage 5 sidewall.Tachometric survey device 92 is angular displacement sensor.
During use, this utility model is installed in the duct by entrance 1 and outlet 7.When there being media flow in pipeline, medium belt moves wheel rotation, and the rotary shaft 8 of impeller starts to rotate, and tachometric survey device 92 starts to measure the rotating speed of rotary shaft 8, and is shown by display 91.It should be noted that owing to radius and the housing of impeller are fixing, the flow of the most each turn is also fixing, then can calculate the instantaneous delivery of pipeline medium.This instantaneous delivery can do a conversion of equal value with the pressure of the medium in pipeline.When force value is excessive, rotating regulating part 2 increases the resistance of impeller, then pressure medium reduces.In display 91, the rotating speed of display reduces the most accordingly.So, there is positively related relation between pressure and rotating speed, after simple conversion, accurate Pressure control or flow control can be carried out.
This utility model provides a kind of pressure-regulating device in pipe network monitoring system, the pressure in pipeline is controlled by controlling the rotary resistance of impeller, medium is made to pass through pressure during valve uniform, it is to avoid rocking of pipeline, safer when making pipeline conveying flammable and explosive substance.And, coordinate the regulation of wheel speed, make pressure more accurate.In addition, moreover it is possible to the instantaneous delivery of medium is monitored, reduce follow-up monitoring difficulty, provide for system and monitor data the most accurately.
Above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with scope of the claims.
